Dr. Cox: OK, here's a bud clearly in need of nipping. Newbie, there are some things that, if they happen, we do want to make a big deal out of them: a cure for cancer, teaching dogs to talk, and you actually managing to walk past the food cart without referring to cream cheese as "cow fudge."
J.D.: I like to play with words.
Dr. Cox: However, of all the things there are to make a big deal out of, can my return to this hellhole please, please, please not be one of them?
J.D.: Well, sure thing, Perry. But, uh, there is one problem.
[J.D. unzips his hoodie to reveal a t-shirt reading "Welcome Back Coxer" with a picture of Dr. Cox with a lot of hair. After Dr. Cox opens the doors to the cafeteria, his colleagues start singing:]
All: Welcome back Your dreams were your ticket out Welcome back To that same old place that you laughed about
J.D.: Well, the names have all changed since you hung around And them dreams have remained since you turned around
Carla: J.D.
J.D.: That's when the background comes in. [singing] Who'd have thought they'd lead you? Who'd have thought they'd lead you? [talking] That's a run I was gonna do, but now is awkward.
Dr. Cox: It's unbelievable.
